Mobile users are forced to use App. The mobile app lacks many features. Please allow login using mobile browsers.
Until there is any missing feature that's a must, and the views must adapt to the screen size and resolution (as all normal sites can do).
I am trying to use Clickup in Firefox' Side View extension (https://blog.mozilla.org/firefox/its-a-new-firefox-multi-tasking-extension-side-view/), but it interprets it as a mobile browser and will not allow me to use the browser view, only click on the option to get the app. At very minimum, it needs to at least have a link allowing us to click through to the browser version of the app.
Just tried using "desktop site" option in chrome for android on my nextbit robin. The desktop site is available but not really usable for me. Every time I try to drag the screen to scroll the side bar is minimized or I grab and drag a task. There is no delay for moving an element of your project vs. scrolling.
